SSC CHSL 2022 PYQ — Question 63

SSC CHSL - 24 May 2022 - Shift 2 • Quantitative Aptitude • Q63

 Inside a triangle ABC, a straight line parallel to BC intersects AB and AC at the points P and Q, respectively. If AB = 6PB, then PQ ∶ BC is _________. 
 

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 5:6. 

AB = 6PB 

Also , AB = AP + PB 

6 PB = AP + PB 

AP = 5 PB 

Hence , APABAP\over AB  = 5PB6PB5PB \over6PB = 565 \over6

Now using Rule, If a line intersects sides AB and AC of a Δ ABC at P and Q respectively and is parallel to BC, prove that = APABAP \over AB = AQACAQ \over AC

So , PQBCPQ\over BC  = 565 \over6
